使用java命令重启tomcat

public static void restartMyTomcat() {
    String location=ConfigUtil.getRestartLocation();
    
    createCmdFile(location);
    executeCmd(location);
      
    
  }

  private static void executeCmd(String location) {
    System.out.println(location);
    Runtime run = Runtime.getRuntime();
    try {
      Process ps = run.exec("" + location + "\\bin\\restart.bat");
      //我很奇怪  下面的代码去掉的话 tomcat的黑框就不能出现  
      BufferedReader br = new BufferedReader(new InputStreamReader(
          ps.getInputStream(), "GBK"));// 注意中文编码问题
      String line;
      while ((line = br.readLine()) != null) {
        System.out.println("StartedLog==>" + line);
      }
      br.close();
    } catch (Exception e) {
      e.printStackTrace();
    }

  }

  private static void createCmdFile(String location) {
    File f = new File(location + "\\bin\\restart.bat");
    try {
      FileWriter fw = new FileWriter(f);
      BufferedWriter bw = new BufferedWriter(fw);
       //下面的必须加上
      bw.write("set CATALINA_HOME=" + location);
      bw.newLine();
      bw.write("call " + f.getParent() + "\\bin\\shutdown.bat");
      bw.newLine();
      bw.write(" ping 127.0.0.1 -n 5  1>nul ");
      bw.newLine();
      bw.write("call " + f.getParent() + "\\bin\\startup.bat ");

      bw.close();
      fw.close();
    } catch (Exception e1) {
      // TODO Auto-generated catch block
      e1.printStackTrace();
    }

  }
